Multiples of a given number are the product of that number and an integer.
Factors of an integer can be identified by checking for a remainder when dividing.
In the statement factor x factor = product, the product is a multiple of each of the factors.
If a is a factor of b then b is a multiple of a

There is often confusion between factors and multiples.

Highlight that the number of dots in an array is the multiple and the number of dots in each column & row are the factors.
